  • Oracle Certified Professional - Java SE 17 Developer (1Z0-829) certification exam was not tough at all for me. The problem with me was that i had anxiety issues. However, i faced the same only while attempting one or two mock tests in the early sessions. Gradually with practice i became used to them and finally i realized that it does not require much to clear the actual exam. If i had knowledge, i will not need anything else.
